SPECIFICATION forming part of Letters Patent No. 330,956, dated November2%-, 1885.

Application tiled September 9, 1885. Serial No. H6568.

.T0 a/ZZ whom, it may concern.-

Be it known that I, FRANCIS X. BRENNER, of the city and county ofPhiladelphia, State of Pennsylvania, have invented an Improvement inAwnings, of which the following is a specification.

My invention has reference to awnings; and it consists, in certainimprovements, fully set forth in the following specication,and shown inthe accompanying drawings, which form part thereof.

In carrying out my invention I provide the usual metal or woodawning-frame at one end with a roller 0r cylinder,upon which the awningis rolled,and from which it is drawn over the-supporting horizontalslats or bars of the frame which is adapted to support it. The rollerupon which it is secured is combined with suit-able ratchet mechanismand an operating chain or cord, which, when pulled, operates the ratchetdevice and causes a rotation of the awning-roller. The ratchet devicebetween the wheelupon which the operatingcord is secured and the rollerto which the awning is secured is thrown out of connection at theterminal of each reverse rotation ofthe cord-wheel, so that normally, ifnot prevented by a ratchet and pawl, the awning may be drawn down orextended. A series of intermittent pulls upon the operating-cord willcause the roller to be rotated and the awning to be wound up. Asimilardeviceis arranged upon the other end of the awning frame, only in thiscase a cord is wound upon the roller, which cord connects with theawning, whereby it may be positively moved in both directions and fixedin any position desired.

In the drawings, Figure l is a side elevation of an awning embodying myimprovements. Fig. 2 is a cross-section of the ratchet-operatingmechanism on line x x. Fig. 3 is a sectional plan view of same on line yy. Fig. 4 is a front elevation of the bracket therefor. Fig. 5 is a sideelevation of the ratchet-wheel. Fig. 6 is a side elevation of the frameor bracket supporting the ratchet mechanism upon the outside of theawning-frame, and Fig. 7 is a front elevation of the said mechanismcompleted.

B represents the supporting slats or bars of the awning-frame, and ofwhich there may be (No model.)

any numberdesired. These bars are arranged substantially horizontal, or,if desired, somewhat obliquely, and are supported at the ou ter end by across-bar, B.

C is the roller upon which the awning D is secured and rolled, and issupported insuitable brackets, F. Secured to the roller C is theratchet-wheel G, having upon its periphery ratchet-teeth, and also beingprovided upon one of its faces with crown ratchet-teeth g. Looselyjournaled upon the roller O, and located between the ratchet-wheel G andthe bracket F,is the operating-cord wheel H, having a groove, h, for thecord or chain M, one end of which is secured to the said wheel. Securedto the face of the said wheel adjacent to the ratchet-teeth g isaspring-pawl, I, having a tongue or extension, I. Normally thespring-pawl I is pressed away from the ratchetteeth g by the tongue Ipressing against the cam projection J on the bracket F. As the cord M ispulled, the wheel H is rotated, and the moment it rotates sutlicientlyto enable the projection ofthe spring-pawl to pass beyond the cam .I thesaid pawl springs into contact with the ratchet-teeth g, and furtherrotation of the wheel H rotates the ratchetwheel G and the rollerGalso.A weighted or spring pawl, K, supported by the bracket F, works inContact with the ratchet-wheel G, and prevents cylinder G from beingrotated and the awning unrolled or extended, excepting when said pawl isdrawn away by a chain or cord, le, and caught upon a hook, L, asindicated in Fig. l. This pawl also holds the ratchet-wheel G whenoperating the wheel H.

j is a stop which prevents the wheel H being rotated more than onerevolution in either direction.

P is a spring,one end of which is secured to the bracket F and the otherend to the wheel H, the object of which is to return the wheel H to itsnormal position and free the pawl I from contact with the ratchet-teethg upon relieving the strain upon the cord or chain le.,

The free end of the awning D is provided with a bar, d, to which issecured the guideroller e, secured together by astrap, E, so arrangedthat the bars B are between them, to the end that the awning was not datorbe free to rise therefrom. The frame B is provided IOO l tion beingshown in Figs. l, 6, and 7.

with just such a ratchet take-up device as above described, With theexception that in place of the roller C winding up the awning the rollerin this instance supports a groovewheel, C', and is adapted to wind up acord or chain, O, connecting with the bottom of the awning at D, or thestrap E, this construc- In this case, as there is no support for a pin,L, for the chain laas hereinbefore specitied,therefore in this case ahook or pin, N, is provided on the frame or bracket F, as shown in Fig.6,by

which the chain may be caught, so as to hold the pawls in contact withthe ratchetwheel, and also in this case a clamp, s, may be used tosecure the bracket F'to the awning-frame B.

By drawing away the pawl K at one end and operating the' cord or chainat the other end the awning may be raised or lowered, or rotated orextended.

While I prefer the construction shown, I do not limit myself to thedetails thereof, as they may be modified in various ways Withoutdeparting from my invention.

Having now described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

l. The combination of the awning with its supporting-roller, a suitablecatch to` prevent its unwinding, an operating cord or chain, achain-wheel,and ratchet devices,substantially as set forth, connectingthe roller and chainwheel,whereby a series of pulls upon the cord orchain winds up the awning, substantially as and for the purposespecited.

2. rIhe combination ot' the awning with its supporting-roller, asuitable catch to prevent its unwinding, an operating cord or chain, achain-wheel,and ratchet devices, substantially as set forth, connectingthe roller and chain- Wheel, whereby a series of pulls upon the cord orchain winds up the awning, and a similar ratchet-and-chain deviceconnecting with the other end of the awning `bya cord and adapted topositively move the awning in the other direction, substantially as andfor the purpose specified.

`3. The awning, in combination with a roller upon which it is wound,mechanism, substantially as described, to Wind up the awning, a similarmechanism to unwind the awning, located at the other end thereof whenextended,

and connected therewith by a cord or chain, and locks at each end toprevent winding or unwinding of the awning except when desired,substantially as and for the purpose specified.

4C. The combination of awning D, roller C, frame F, ratchet-wheel G,having teeth g, chain-wheel H, having spring-paw] I, spring P, camprojection J, and chain M, substantially as and for the purposespecified.

5. rIhe combination of awning D, roller C, frame F, ratchet-Wheel G,having teeth g, chain-wheel H, having spring-pawl I, spring P, camprojection J, pawl K, and chains M and la, substantially as and for thepurpose specified.

6. The combination of awning D, roller C,

frame F, ratchet wheel G, having teeth g, chain-Wheel H, havingspring-pawl I, spring P, cam projection J, having stopj, and chain M,substantially as and for the purpose specilied.

7. rIhe combination of frame B B', awning D, roller G, frame F,ratchet-Wheel G, having teeth g, chain-wheel H, having spring-pawl I,spring P, cam projection J, and chain M, substantially as and for thepurpose specified.

8. rIhe combination of frame B B', awning D, having guide-rollers e,roller G, frame F, ratchet-wheel G, having teeth g, chain-wheel H,having spring-pawl I, spring P, cam projection J, and chain M,substantially as and for the purpose specified.

9. The combination of frame B B', awning D, roller C, frame F,ratchet-Wheel G, having teeth g, chain-'wheel H, having spring-paw] I,spring P, cam projection J, chain M, and a similar ratchet-actuatin gdevice secu red to the frame B, and connected with the awning by a cord,O, substantially as and for the purpose specified.

l0. The combination of the frame F, having clamp-jaws f and providedwith pin N, with spring I?, chain-Wheel H, having pawl I, ratchet-WheelG, having wheel C and ratchetteeth g, and shaft C, substantially as andfor 'the purpose specied.

In testimony of which invention I hereunto set my hand.
